2 Claims. (Cl. Ztl-55) This invention relates to windows of the doublesash sliding type and particularly to mechanism adapted to connect theinner sash to the outer sash in such a manner as to cause the outer sashto be closed automatically when the inner sash is closed.

Heretofore in air conditioned or heated homes, apartment houses andother buildings where independently slidable outer and inner sashes areused, much of the insulating value of outer sash has been lost becauseof the failure of the occupants of the buildings to close the outer sashwhen the inner sash is closed, after both have been opened. Failure ofthe tenants of apartment houses to close the outer sash is particularlytroublesome and expensive for the landlords who furnish air conditioningservice or fuel for heating the building because the tenants or guestsfrequently, after opening the windows of sleeping quarters at night,fail to close the outer or storm sash when the inner sash is closed fordaytime occupancy.

The present invention has for its principal object to provide forwindows of the class described simple and readily attachable means forautomatically actuating the outer sash to closed position when the innersash is closed.

Another object is to provide an attachment of the class described whichmay be securely and easily fastened in operative relation to both sashesduring the winter or other season when the insulating value of the stormsash is needed and readily removed when the storm sash is not needed.

A further object is to provide an attachment of the class describedwhich guards against the unauthorized opening of the outer sash when theinner sash is locked in either closed or slightly open position.

My invention also includes certain other novel features of constructionwhich will be more fully pointed out in the following specification andclaims.

The invention will be best understood by reference to the accompanyingdrawings which illustrate, by way of example and not for the purpose oflimitation, a preferred embodiment of my invention.

In the drawings:

In the drawings a window of conventional type is shown ited States atentCil ice

as having a frame indicated generally by the numeral '7, a sill 8 andinner and outer vertically sliding sashes. Each of these sashes hasupper and lower relatively slidable members. The lower inner sash,indicated generally by the numeral 9, has a lower rail 10 and an upperrail 11 and is guided in the usual manner between stop and partingmembers 12 and 13 (Fig. 3). Similar guides are provided for the uppermember 14 of the inner sash.

Mounted in outwardly spaced relation to the inner sash is an outer orstorm window having a lower sash 15 and an upper sash 16 which areslidable vertically between suitable guides indicated generally by thenumeral 17. This window is of a conventional metal type including astorm sash and a screen. The outer sash 15 has a bottom rail 18 andstile members 19 litting in the guides 17. The upper sash 16 may bemounted in a common plane with a screen 20 in conventional manner.

Pairs of connecting members 21 and 22 are provided to operativelyconnect the inner sash 9 to the outer sash 15. The members 21 arestrong, rigid arms fastened at one end to the lower rail 18 by means ofa bar 23 which is preferably formed with a channel 24 extending alongits upper edge to receive the lower marginal portion of the rail 18. Thebar 23 is also formed with a bottom channel groove to receive a flange25 formed on a fixed lower frame member 26 of the outer window frame.Mounted centrally on the bar 23 is a lock 27 adapted to be actuated by aremovable key 28 (Fig. 5) to fasten the bar to the lower rail 18 of thesa'sh 15. A keeper 29 is fastened on the rail 18 to receive andinterlock with the bolt of the lock 27.

As best shown in Figs. 4 and 5, the bar 23 carries at each end a latchpin 30 which is spring biased to project into apertures formed in thevertical guides 17 of the outer sash. A handle 31 projects from each ofthe pins 36 through an elongated slot 32 formed in the inner side of thebar 23. The slots 32 are approximately L-shaped, having verticallyextending portions 32a into which the handles 31 may be moved to retainthe latch pins 30 in retracted, inoperative position.

As viewed from the side, the connecting members 21 are substantiallyZ-shaped and have end portions 21a which are rigidly secured to the bar23. The opposite end portions 2lb of the members 21 project beneath theconnecting members 22 which are rigidly fastened to the rail 10 bybrackets 33 carried by the end portions of the rail. A bracket 33 may beformed integrally with each of the members 22 and may be secured to therail 10 by means of screws or other suitable fastening members, asindicated in Fig. 6. It will thus be evident that the connecting members22 project into the path of the inner end portions 2lb of the members 21so that when both sashes are in open positions and the inner sash 9 ismoved downward to closed position, the connecting members 21 and 22 areoperative to close the outer sash 15.

To install my attachment on sliding sashes of the common type described,the bar 23 carrying the connecting members 21 is placed in engagementwith the lower marginal portion of the rail 18 and fastened inengagement therewith by operation of the lock 27, whereupon the key 28may be removed to guard against unauthorized removal of the outer sashattachment. The connection between the outer and inner sashes iscompleted by fastening the brackets 33 carrying the members 22 to theouter surface of the rail 10 in proper vertical alignment with the innerend portions 2lb of the members 21. In cases where it is desirable toprovide for the locking of the outer sash 15 in closed and/ or partiallyopen positions, the side guide members 17 for this sash are drilled atsuitable intervals to provide sockets to receive the outer ends of thepins 30. This makes it possible to lock the outer sash with its bottomrail either in fully closed position or at any selected elevation, e.g., that indicated in broken lines in Fig. 1.

ln operation, the inner sash member 9 may be raised to any openposition, in the usual manner, without regard to my device because myconnecting members 22 are separate from the members 21, Aft'er movingthe inner sash to open position, the outer sash may also be raised tocorresponding open position or to any position at a lower elevation inthe usual manner. if the latch pins 3) are used to lock the outer sashin closed or other selected position, these pins may be actuated toretracted position to permit opening of the outer sash by manipulation othe handles 31. Subsequently, when it is desired to close the window,the latch pins may be retracted from their operative position and theinner sash 9 moved downward to closed position in the usual mannerthereby automatically, by operation of the connecting members 21 and 22,closing the outer sash 1S. It will be evident that with my attachmentproperly installed, the inner sash cannot be closed without closing theouter sash also.

My attachment constitutes a safeguard against the unauthorized openingof both sashes from the exterior of the building when the inner sash issuitably fastened in either closed or slightly open position.

When the insulating value of the outer or storm sash is not required,the members 21 connecting the outer sash to the inner sash may bequickly and easily removed after merely operating the lock 27 todisconnect the bar 23 from the rail 18.

I claim:

l. For a window having outer and inner sliding sashes and first andsecond rail members of the respective sashes disposed in parallelrelation one to the other, an attachment comprising, a rigid bar adaptedto extend along and in contact with the first rail member, said barbeing laterally coextensive with said rail member, means for detachablyfastening said bar to said first rail member, a first pair of rigidconnecting members projecting from said bar toward the inner sash atwidely spaced points along said bar, and a second pair of connectingmembers carried by the second rail member and projecting therefrom intothe path of said connecting members of the first pair whereby said outersash may be actuated to closed position when the inner sash is closed.

2. For a window having outer and inner substantially vertically slidingsashes and rst and second lower rail members of the respective sashesdisposed in parallel relation one to the other, an attachmentcomprising, a rigid bar formed to t in engagement with said lirst railmember and being laterally coextensive therewith, means including a lockhaving a removable key for detachably fastening said bar to said firstrail member, a first pair of rigid connecting members projecting fromsaid bar toward the second rail member, and a second pair of connectingmembers carried by the second rail member and projecting therefrom intothe path of the connecting members of said first pair whereby said outersash is actuated to closed position when the inner sash is closed.
